Work timecalculator

Enter the laser excitation wavelength (nm) and Raman shift either in nanometers (nm) or wavenumbers (cm-1) in order to convert units of the Raman shift.

Raman spectroscopy is a form of vibrational spectroscopy technique where vibrational, rotational frequencies and low-frequency modes of a system caused by the inelastic scattering of light (the Raman shift) are monitored. These vibrational frequencies are used as chemical fingerprints for the identification of molecules. Usually, Raman shifts are typically in wavenumbers, which have units of inverse length (cm-1). In order to convert between spectral wavelength, wavenumbers and frequency of shift in the Raman spectrum, we have developed this applet to compute Raman shifts and bandwidths.
